13.4 Images Formed by Lenses
IntermediateMCQMathematicalConceptual13.7k
A horizontal dashed line represents the principal axis. Two thin converging lenses are drawn as vertical line segments with outward-pointing double-arrow tips at top and bottom. The first lens, labeled Lens 1, is positioned along the axis with tick marks labeled F1 at a distance representing 10 cm on both sides. The second lens, labeled Lens 2, is positioned 40 cm to the right of Lens 1 along the axis, with tick marks labeled F2 at a distance representing 15 cm on both sides. An upright arrow labeled Object stands on the principal axis at a distance representing 15 cm to the left of Lens 1. No light rays, intermediate images, or final images appear.
Two converging lenses on a common principal axis.
Two thin converging lenses, Lens 1 with focal length \(f_1 = 10 \text{ cm}\) and Lens 2 with focal length \(f_2 = 15 \text{ cm}\), are positioned along a common principal axis separated by a distance of \(40 \text{ cm}\). An object is placed \(15 \text{ cm}\) to the left of Lens 1. What is the distance of the final image from Lens 2, and is the final image real or virtual?
